NUT LOCK.

SPECIFICATION forming part of Letters Patent No. 426,387, dated April22, 1890.

Application filed April 19, 1889, Serial No. 307,750- (No model.)

To all whom it may concern.-

Be it known that I, GEORGE M. KIFER, a citizen of the United States,residing at Penn Station, in the county of \Vestmoreland and State ofPennsylvania, have invented a new and useful Nut-Lock, of which thefollowing is a specification.

My invention relates to improvements in nut-locks; and it consists incertain novel fea tures hereinafter described and claimed.

I11 the drawings, Figure 1 is a perspective View showing my improvednutlock applied to a rail-joint. Fig. 2 is a plan view. Fig. 3 is adetail perspective view of the lockingplates.

The ends of the rails are provided with bolt-holes in the usual manner,and the fast ening-bolts are .inserted through the same and thefish-plate, as will be readily understood.

In carrying out my invention the bolt A is inserted through the end ofone rail and the fish-plates, and the nut B thereon is turned home inthe usual manner. The lockingplate 0 is then arranged again st thefish-plate, with the opening D therein registering with the bolt-holes,after which the bolt B is inserted through the said bolt-holes and thenut E thereon turned home against the locking-plate. This locking-platemay be of any desired length, and it is provided at one end with thefiat rib or flange F, which is adapted to bear against the side of thenut B, and thereby prevent the same from turning. At the opposite end ofthe locking-plate O, I pro vide an integral post or lug G, on which alatch II is pivoted, and the said latch is provided with a fiatend,wl1icl1 bears against the side of the nut E, so as to prevent thesame from turning. The lug or post G is provided with an angular outerend, and a spring I, secured on the latch H, bears against the end ofthe said lug, so as to prevent the latch being accidentally raised fromengagement with the nut E.

In order that the latch may be easily disengaged from the not when sodesired, I form in its sides atits free end the recesses or notches J,which provide the ribs K, so that the said latch can be easily graspedby the fingers of the operator, to be raised.

From the foregoing description, taken in connection with theaccompanying drawings, it is thought that the advantages of my devicewill be readily seen.

By the use of my improved device the nuts will be effectually heldagainst turning and the locking-plate be secured in position.

The locking-plate is secured in placeby the nut on one of thesecuring-bolts and can be easily and rapidly applied to any rail-jointnow in use.

My device is very simple and can be manufactured and sold at a slightexpense.

Having thus described my invention, I claim- A nut-lock consisting,essentially, of a lock ing-plate provided at one end with a transverserib F and at its other end with an integral lug or post G, having anangular outer end, a lat-ch pivoted at one end on said lug and providedat its free endin its sides with notches or recesses J, and a springsecured on said latch and bearing on the outer angular end of the postor lug, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
